Description:
This ancient green organism was found living in an acidic lake. Archaeologists have in the same lake found microscopic fossils of a—now extinct—predator species thought to once live off of these green creatures. To corroborate this theory we would like to see if there are some traces of their interaction left in the genome of the green species. To test our theory we have placed a synthetic predator species on this substrate to see if some protective mechanism can be awoken from the depths of the green swimmers genome. That didn\'t happen.
Upon inspection of the genome we have found that a recent mutation has taken a shortcut, the M3 cells no longer split to M5,M6, but it splits to M3,M4. Perhaps this mutation proliferated as a result of the extinction of the predator? Anyhow, can you—without inserting a keratinocyte—restore the old behavior and see what the species does in this synthetic environment?
If you get 400 cells without actually introducing a keratinocyte then we have confirmed that this species has genes to protect itself from the predator and thus the fossil predators were most likely once living off of this organism
